WHAT DOES OIL SLUDGE DO?
Oil sludge is like a gel that sticks to your engine parts and blocks oil galleries preventing the normal flow of oil throughout the engine. Normal oil flow provides maximum wear protection and aids with the cooling of the engine. Sludge actually stores heat rather than releasing it putting added stress on the radiator and cooling system. It also reduces oil pressure and fuel economy and will lead to component wear and potential failure of expensive components such as timing belts, idle controls, etc. WHAT CAUSES SLUDGE? Unfortunately there is no one simple cause of sludging.
